IMPROVEMENT IN CARRIAGE-SPRINGS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, Srnxnr STEWARD, of. Trenton, in the county of Mercer and State of New J ersey, have invented a certain Improvement in Carriage- Springs; and I do hereby declare that the following is a full, clear,.and exact description thereof, reference be-.

ing had to the annexed drawing, making part of this specification, in whieh-- Figure 1 is an elevation of my improved carriagespring, showing its attachment to the axle.

Figures 2, 3, and 4 are plan views of the different parts constituting such spring.

The same letters are used in all the figures in the designation of identical parts.

This invention relates to springs for carriage-s and other vehicles; and

My improvement consists in attaching the ends of a semi-elliptic spring, upon the convex side of one or,

more of which the body of" the vehicle is to be supported to the axle, by means of two diagonal springbraccs, the latter passing from the points of attachment to such semi-elliptic spring diagonally past-each other to points near the journalspof the axle, there to' scribing witnesses.

H represents the semi-elliptic spring, composed, as usual, of plates of steel, the lower and longest one oi -which is hook-fashioned at, its ends, and provided with perforated ears, to receive bolts, by which the spring-braces A and B are jointed to it.

Each spring brace, which may also be composedof laminae of steel, as shown, extends from the point of attachment to the semi-elliptic spring diagonally beyond the opposite end of, the'latter and is secured to the axle 0, near its journal, by means of a sleeve and set-screw, as shown, or in some other suitable manner, abutting endwise against the dollar a on said axle.

In order that said spring-braces may pass each other, they are bent at the ends, as clearly indicated in figs. 3 and 4.

Vhat I claim as my invention, anddesire to secure by Letters Patent, is p The carriage-spring herein described, composed of the semi-elliptic spring H and diagonal spring-braces A and B, substantially as set forth.

In testimony whereof, I have signed my name to the foregoing specification in the presenceof two sub- SIDNEY STEWARD.
